Despite the wording of the closing reason, the question is off-topic in Super User as was mentioned by Mokubai, it might be on-topic in other Stack Exchange sites but I stronghly recomment that it be improved before posting it again.
If you really want to go deep in understanding how the platform that supports Super Users and the other sites in the Stack Exchange network choose the close reasons please read How does the system determine which one close reason should be displayed on a closed question, given the close votes?.
Most of the questions about web applications like Google Sheets are off-topic in Super User. Questions about using Google Sheets are on topic in Web Applications SE and the questions related to programming (i.e. formulas) are on topic in Stack Overflow too.
Some questions related to Google Sheets might be found in Super User because they are about spreadsheet formulas that are compatible with Excel and other spreadsheet applications that are on-topic.
Also there might be some google-spreadsheet questions because they are related to something that is on-topic in Super User like a web browser, i.e., questions about a web browser or Internet error. Below are some examples related to firefox:
Major FIREFOX Redirect Error Problem (Error Code 11156)
In this case, IMHO, gmail, facebook and google-spreadsheets should be removed.
Override font smoothing (antialiasing) method in Google Sheets grid (Firefox)
In this case the question is about using the web browser developer tools to override some default behavior.

I strongly recommend to search and research thoroughly before posting your question on a Stack Exchange site. Share what you found and why it didn't meet your needs.
When posting almost any question on Web Applications SE and Stack Overflow about Google Sheets:
Describe the structure of your spreadsheet
Include sample data as text both for input and the corresponding expected result when this be apropriate.
Show what you have tried.
Include link to the most relevant relate questions from the respective site.
Do not cross-post across Stack Exhange sites.
If you will cross-post across external communities, include links if you already have done that.
NOTE: Contrary as Stack Exchange sites do, other sites like Google Product Communities might not allow to update posts after some time, so I recommend to make your post in a Stack Exchange site were it be well received, as the place to keep track of the progress / share updates.
Specific about your question
Don't include tags in titles. Ref https://superuser.com/help/tagging
Don't use microsoft-excel as a common name for spreadsheet / on questions about Google Sheets
Avoid using rethorical / side questions like
as some people might think that the question "needs more focus" for including multiple questions in a single post.
Use A1 notation (preferred) or R1C1 notation instead of just letters like A, W.
Recommended: in data tables use consecutive letters as column headers an consecutive numbers as row headers, i.e.
NOTE: In relation to 3, 4 and 5, when asking "complex formulas" questions you should show that you know the basics about working with spreadsheet formulas and that your are familiar with the formula syntax, formula bar, the funcion list, by using the proper spreasheet / Google Sheets terms and showing the formulas that you have tried, the resulsts as well the error messages if there are any.
There are no restrictions regarding expertise level using Google Sheets (beginner, advanced) but it's expected, as mentioned previously, that the asker have searched the site, and in this case including, the Google Sheets section in the Google Editors Help Center thoroughly before asking the question, and that the findings and why they didn't meet the needs be shared in the question.
Note: You might find user asking to share a spreadsheet. This is up-to you, sharing the spreasheet doesn't replace the requirement to include all the relevant details directly in the question body as questions should be self contained whenever be posible (i.e. Excel files can't be attached).
